ELEVATOR-BUCKET.

SPECIFICATION forming part of Letters Patent No. 788,590, dated May 2,1905.

Application filed December 2, 1904. Serial No. 235,156.

To all whom it may concern.-

Be it known that I, Gnone NIKEL, a subject of the Emperor of Germany,residing at Geislingen, in the Kingdom of Wiirtemberg, Empire ofGermany, have invented a new and useful Elevator-Bucket, of which thefollowing is a specification.

Myinvention relates to that class of buckets or cups which are commonlyattached in se ries upon an endless chain or belt for the pur pose ofconveying grain or other loose material in bulk from one point toanother.

My invention has forits object the elevation of a maximum amount ofgrain in the cheapest and most convenient way and with the leastexpenditure of power. As compared with the elevator-buckets nowin commonuse the invention under consideration is believed by me to be cheaperand simpler in construction, and the buckets are capable of being placedcloser together upon the carrier-belt, while they may be operated withless power and more rapidly and with greater efficiency in filling andemptying the load.

In the accompanying drawings, forming part of this specification, Figurel is a perspective view of a complete bucket embodying my invention.Fig. 2 is a side elevation of the bucket, and Fig. 3 is a plan of theblank which when bent into shape constitutes the entire bucket.

The lower part A of this bucket has the form of an inverted pyramid,which form facilitates both the filling and the emptying of the buckets,as well as the placing of the buckets close together upon the elevatorchain or belt, and makes possible the use of the cups for all kinds ofmaterial with like success. The upper part or mouth B of the bucket, asshown, consists of four sides, three of which are substantiallyvertical, while the fourth (which is attached to the belt) forms acontinuation of one of the inclined faces of the pyramid, and I havefound that this construction makes an undue spreading of the contentsafter emptying impossible and at the same time increases the capacity ofthe bucket.

It is obvious to those skilled in the art that the construction of thecompleted device (shown in Figs. 1 and 2) from the blank (shown in Fig.3) is simple and cheap, without in any way impairing the strength orefficiency of the bucket. The blank is bent along the broken lines O, sothat the faces D D are brought together. The flanges E are turned up(from the lines G) into vertical position to form, with the upper partof the united faces D D of the blank, the walls of the mouth of thestructnre, which is substantially quadrangular in section, while thetriangular portions of the blank form the converging sides of the bottomof the bucket.

The above-described walls of the buckets month are riveted or boltedtogether at F F, and the completed buckets may then be attached by boltsor otherwise to the carrier through the openings G G, which respectivelyregister with one another.

In use the buckets are attached to the endless chain or belt in theusual manner, except that they may be placed nearer together than ispossible with the devices now in use.

It is obvious that the device above described may be used for conveyingmany other substances than grain, and I do not confine the claims to useon grain-elevators.

Having now described my invention, what I claim as new, and desire toprotect by Letters Patent, is-

1. An elevator-bucket, the lower portion of which, when inverted, hasthe form of a pyramid, while the upper portion has substantiallyvertical sides, whereby both the filling and emptying of the material isaccomplished with a minimum amount of energy.

2. An elevator-bucket, constructed of a single blank and consisting of alower portion in the form of an inverted pyramid and an upper portion,one wall of which is an extension ofthe rear wall of the pyramid, whilethe other walls of said upper portion are vertical.

3. A pyramid-bucket for grain-elevators, the upper portion of which hassubstantially vertical walls, whereby the spreading of thecontents,after leaving the bucket,is prevented.

4-. An elevator-bucket, comprising a lower and an upper portion, thewalls of said lower to this specification in the presence of twosubportion converging toward a point at its base, scribing witnesses.while the upper portion forms a month, one wall of which is an extensionof one side of (IEORG NIKEL' 5 the converging base, While the othersides are Witnesses:

substantially vertical. WM. HAHN,

In testimony whereof I have signed my name ERNST ENTERMANN.
